Preliminary PT2312E

Stereo Audio Processor for Car Audio

DESCRIPTION

FEATURES

The PT2312E is an audio processor designed for

versatile application, includes 4 stereo input selector

with adjustable gain, master volume control with low

frequency loudness compensation, individual output

attenuator and tone control. It is a good solution for the

car audio signal processing.

•

4 stereo inputs with gain selection, range from 0dB

to +11.25dB in 3.75dB/step

Master volume from 0 dB to -78.75dB in

1.25dB/step

Speaker attenuator for balance and fader, range

from 0dB to -38.75dB in 1.25dB/step

Each channel output can be muted individually.

Low frequency loudness compensation

Bass and Treble control, range from -14dB to

+14dB in 2dB/step

•

Due to the high reliability requirement from the audio

business, the PT2312E improves both audio

performances and input surge current capability, these

causes the PT2312E is the best solution for the

cost-effective audio systems.

•

Wide operation range (VDD = 4V to 10V)

Improved and replace PT2312 and PT2312A
